Abstract: A portable facsimile equipment having a plurality of power source connecting portions adapted to be selectively connected to plural kinds of power sources. The facsimile equipment is operable in correspondence with the kind of power source connected thereto. A power source kind detector detects the kind of power source connected. A communication mode storing device stores a communication mode corresponding to the power source connected. A communication mode selecting device accesses the communication mode stored in the communication mode storing device according to a signal from the power source kind detector to automatically set the communication mode. A compact battery can be detachably fixed as one of the power sources. An AC power source can be detachably fixed as one of the power sources. A DC power source can also be detachably fixed as one of the power sources.

Abstract: A postal charge processing system includes a weight measuring unit for measuring the weight of a postal parcel and producing weight data corresponding to the measured weight, a keyboard having a plurality of keys selectively operated to set postal conditions, a memory for storing postal condition data produced in accordance with key-in operations in the keyboard, and a data processing unit for calculating the postal charge based on the weight data from the weight measuring unit and the postal condition data stored in the memory and subsequently clearing the postal condition data stored in the memory. It further includes a counter, which functions to count up one count in response to a count-up signal produced from the data processing unit upon detection of the removal of the postal parcel from the measuring unit on the basis of the weight data from the measuring unit after completion of calculation of the postal charge in the data processing unit.

Abstract: A postal charge processing system includes a measuring unit for measuring the weight of a postal parcel and producing weight data corresponding to the measured weight, a plurality of keys for setting postal conditions including the way of mail and region of destination and a data processing unit for calculating the postal charge on the basis of postal condition data generated by selective operation of the plurality of keys and weight data supplied from the measuring unit. It further includes a memory for storing at least part of the postal condition data produced with the selective key operation and a repetition key. When the repetition key is operated, it permits the data processing unit to read out the postal condition data from the memory and calculate the postal charge based on the read-out postal condition data and weight data supplied from the measuring unit.

Abstract: A postal charge processing system, which comprises a postal charge calculator for calculating the postal charge of a postal parcel from weight data corresponding to the weight of said postal parcel and post condition data concerning post conditions for the postal parcel including the way of mail and region of destination. A memory, numeral keys which are operated when writing a desired fee data in said memory, a clear key for clearing the data in the memory, a meter stanp issue key operated when issuing a meter stamp corresponding to the data in the memory and a meter stamp issuing unit including a data processing unit for controlling the memory in accordance with the operative state of the afore-said various keys, is provided. The data processing unit is set to a clear key lock state at the time when a predetermined bit of charge data calculated by the calculator is transferred therefrom to the memory, and in this state it nullifies key-in data produced with the operation of the clear key.

Abstract: A postal charge processing system includes a data processing unit calculating the postal charge of a postal parcel from weight data representing the weight of the postal parcel and postal condition data about postal conditions such as the way of mailing and region of mailing destination and means for displaying the postal charge thus obtained on a charge display unit while displaying the weight data on a weight display unit. It also includes a memory for storing the maximum permissible weight data and an overweight display unit, and the data processing unit calculates the difference between the measured weight data and the maximum permissible weight data stored in the memory when it is detected that the former weight data is greater in value than the latter and supplies the weight difference data thus obtained to the overweight display unit for display thereon.
